FYI: fix help for catch catch and catch throw

[Tom Tromey]

I'm checking this in.

The help for "catch catch" and "catch throw" claims that they take an
exception name as an argument.  They do not -- this was never
implemented and most of the other references to it were removed some
time ago.

Built on x86-64 F15.
